Page 17 REPLACEMENT PARTS If replacement parts are necessary, use only genuine LEHR parts or parts of the same type and of equivalent strength and materials. Any part of inferior quality may malfunction, and the resulting loss of control could endanger the operator and passengers.
Page 18 Oily or dark color ceramic could indicate a malfunction. Do not attempt to diagnose any problems yourself. Instead, take the outboard motor to a LEHR dealer. You should periodically remove and inspect the spark plug because the electric arcing will cause the spark plug to slowly erode and the gap will increase.
Page 19 If you have difficulty verifying the idle speed, or the idle speed requires adjustment, consult a LEHR dealer or other qualified mechanic. 2. Verify whether the idle speed is set to specification (1050 + 150 RPM). Adjust the speed by turning the idle speed screw with a phillips head screw driver.
